Billy said "Stephanie wants the Willow Pattern" so I wonder if he's selling it to her! It sounds as if he's trying to cut down on his collections of stuff and maybe trying to sort out and organise his life and himself. If so, good luck to him.If only SJ could do likewise!
What some seem to forget is that Michael doesn't actually, personally own a property where he can display/store all his collections. Not entirely sure what the situation is with regard to the Cottage, but it is small and, unfinished so he currently can't live there no matter how hard Billy and Mick try to make Michael see sense in doing. And, again, as far as I am aware, it is ultimately owned by Billy and Gwen - please feel free to correct me if I am wrong.
He currently occupies a bedroom in the chateau too, again, owned by Billy and Gwen. Which, gleaned from posts on this site, I think they are planning to rent out or some such other opportunity in the pipeline, this year.
All that china has been sitting on the Chateau's dining room table since just after NY. Time for it to go/be sold or, packed up and stored somewhere else on the property.
TBH, if I were Michael's parents/family, I would be extremely worried about him, as I am 100% certain they currently are. BUT, if he is going through some kind of addiction/mental health situation, then, you can only lead the horse to the water, you can never make it drink - unless that horse wants to. And, how many times have they been through this exact same situation during the past 2/3 years? Such a shame as originally Michael displayed so much promise.
